Dory is a fictional blue tang fish and a major character of Pixar's animated film series Finding Nemo.

However, her childlike optimism and ability to communicate different languages from both humans and whales have helped both her and Marlin advance their quest to find Nemo.

[3] Upon the production of Finding Nemo, Ellen DeGeneres brought concerns upon the producers of the film due to the comedian potentially lacking the ability to cue dramatic lines and performances.

Her blood's scent sends Bruce into a frenzy and he accidentally sets off naval mines that knock Marlin and Dory unconscious.

Marlin and Dory meet Nigel the pelican, who knows about Nemo and offers a ride to his location, which they do after a swarm of seagulls attempt to eat them.

Though she initially forgot who he was, she remembers after reading a logo on a pipe and returns him to Marlin until she gets captured in a fishing net alongside a school of groupers.

Through flashbacks, it is revealed that Dory got separated from her parents, Jenny and Charlie, as a child and eventually forgot about them due to her short-term memory loss, then joined Marlin to find Nemo.

During a field trip in Nemo's class, Dory has a flashback about her parents, only to be swept away by a school of eagle rays.

Dory, Marlin, and Nemo ride Crush through the California Current to their destination, where they explore a shipwreck full of cargo.

Dory accidentally awakens a giant Humboldt squid while attempting to call for her parents, but the three trap it in a large shipping container just before it devoured Nemo.

Hank, who fears being released back into the ocean, agrees to help Dory find her parents in exchange for her tag.

While in the habitat, Dory notices her parents are gone, which reminds her why she went lost in the first place: she was pulled away by an undertow current out into the ocean while she was getting a shell to cheer up her mother.

After being told by a hermit crab that her species was being held in the aquarium's quarantine, Dory would go through the same pipe that swept her away, to which she would eventually reunite with Marlin and Nemo searching for her.

Destiny and Bailey would attempt to guide the trio into the aquarium's quarantine, which the other blue tangs tell them that Dory's parents escaped from the institute a long time ago to search for her, only for them to never come back.

Dory and her parents go back to the institute to save Nemo, Marlin, and Hank from a truck that's transporting them to Cleveland, with Destiny and Bailey helping them.

Hank begins to adapt a happy lifestyle in the ocean and also becomes a substitute teacher for Nemo's school as Mr. Ray goes on migration.

Dory's species, the blue tang, saw a spike in sales among fish owners and aquarists after the release of Finding Nemo.

In-line with the release of Finding Dory, the University of Florida's Tropical Aquaculture Laboratory managed to successfully breed blue tangs in human care.

Dory has also been praised for her sympathetic, dramatic moments, particularly when she attempts to sympathize with a depressed Marlin before he leaves her after failing to rescue Nemo before his supposed 'death'.
